REPL utilities. This package provides additional utilities when working with node projects in repl. At the moment two helper function are exposed:

  • doc prints documentation for the given function if documented as defined in expected format (
  • use requires given module and puts all it's exports into the scope (For details try doc(use))


To use this repl-utilitis form your package add it to your devDependencies and optionally add npm script "repl": "node node_modules/repl-utils". Example package.json file will look as follows:

  "name": "my-package",
  "version": "0.0.1",
  "description": "my package description",
  "devDependencies": {
    "repl-utils": ">=1.0.0"
  "scripts": {
    "repl": "node node_modules/repl-utils"


From your package dir run

npm run repl

And from the repl you'll be able to use:

doc(doc) // try this: 
function doc(source) { ... }
Prints documentanion of the given function
doc(use) // Now this: 
function use(id, options) { ... }
Like `require`, but also copies exports from the given module to the current
context. Optionally `options` can be passed to limit imports.
use('fs', { only: [ 'readFile' ] })     // only imports readFile
use('fs', { as: { writeFile: write })   // imports fs.writeFile as write
use('fs', { reload: true })             // reloads module
// Enjoy hacking!
